Atomic mass is the concept related to a single atom, whereas molecular mass relates to a group of atoms. If you are planning to proceed with this concept, then it is necessary to gain precise … Mole can be defined as the amount of substance that contains the same number of entities (atoms, molecules, ions etc) as the number of atoms present in 12g of the carbon −12 isotope. Define mole fraction. A solution of sucrose in water is labelled as 20 % w/w. What would be the mole fraction of each component in the solution? 2 mole of an ideal gas undergoes isothermal compression along three different paths (i) reversible compression from P = 2 bar and V = 4 L to P, = 20 bar (ii) a single stage compression against a … Find the average translational kinetic energy per molecule if one mole of the gas is contained in a volume 1.23×10−3 m3 at a pressure 2×105N /m2. Avagadro's number is 6.02×1023 molecules/moles A balloon blown up with 1 mole of gas has a volume of 480 mL at 5∘C, the balloon is filled to (7/8)th of its maximum capacity. Find the minimum temperature at which it will burst. NCERT Solutions for Class 11 Chemistry Chapter 1 – Some Basic Concepts of Chemistry In this chapter, laws of chemical combination, Dalton’s atomic theory, mole concept, empirical and … Gravimetric analysis Volumetric analysis We can solve the problems on gravimetric and volumetric analysis by using the two well-known concepts of mole concept and the concept of equivalence. To … For the combustion of 1 mole of a liquid benzene at 25oC, the enthalpy is given by: C6H 6(l)+ 15 2O2(g) → 6CO2(g)+3H 2O(l) ΔH =−780980 cal What would be the internal energy of the reaction? At 88 0 C benzene has vapour pressure of 900 torr and toluene has a vapour pressure of 360 torr. What is the mole fraction of benzene in the mixture with toluene that will boil at 88 0 C at 1 atm. pressure, …
